Flatfoot (Surgery) Flashcards
When to consider surgical intervention?
1?
2?
3?
4?
5?
- Painful flat foot not responsive to conservative care
- Orthotics
- AFO
- Bracing
- NSAIDS
How to approach surgery option for flatfoot?
1?
2?
3?
4?
5?
- Age of the patient
- Flexible Vs Rigid
- Planal dominance
- Radiographic measurements
- Is Equinus present
What are the general procedures for flatfoot?
1?
2?
3?
4.?
5?
- Soft tissue procedures
- Arthroeresis
- Osteotomies (Depending on the planal dominance)
- Soft tissue/tendo transfers and osteotomies
- Fusion/arthrodesis STJ/ medial column (stage 4, when doesn’t reposnd to anything else)
What is happening here?
Synovectomy of the PTT
What’s Young’s tenosuspension?
1?
2?
- another soft-tissue procedure rerouting of tibialis anterior tendon to bring it more plantarly so that stabalise the medial longitudinal arch distally
- doing this will not change the rearfoot positionit will increase the forefoot abduction
Kinder procedure (based on lecture notes)
1? is identified within the substance of the tendon and is 2?
If the 3? is to be rerouted through the navicular, it is detached as 4? as possible
If there is a significant prominence to the 5?
Rerouting PTT by drilling a hole plantarly to dorsally, passing the tendon through the whole and suturing it to it self
OR Mitek anchor
- The accessory navicular or os tibiale externum
- excised with sharp dissection
- tibialis posterior tendon (PTT)
- distally
- medial tuberosity of the navicular, it is osteotomized and resected
What’s the function of Mitek anchor?
To anchor tendon to bone
The concept of arthroereisis:
The concept of arthroereisis is the insertion of a device in the 1? to block 2? against the 3? during 4? which is prolonged in the flexible flatfoot.
- Sinus tarsi 2. the contact of the lateral process 3. calcaneal sinur floor 4. maximum end-range pronation
Some facts about arthroereisis:
Useful for 1?
2?
3?
Blocks 4?
- flexible flat foot
- Paediatrics
- Posterior tibialis function
- STJ pronation
What’s the name of the implant used in arthroereisis?
Hyprocure
Lateral column lengthening /Evans
Painful 1?
2? adult acquired flat foot
Significant 3?
It has allowed patients with more severe deformity to gain adequate correction of the triple joint complex
- pes plano valgus
- Stage 2 (The books says stage3)
- transverse deformity (the forefoot is ABducted)
Evan’s as illustrated by Coughlin and Mann
An incision is made 1?
Once on the floor of the sinus tarsi, dissection is made 2?
3? is placed as a guide for the osteotomy cut
To avoid too small a distal fragment 4?
Make the cut, taking care not to plunge through the medial cortex
Open the osteotomy site laterally insert 5?
Fixation with 6?
- longitudinally along the sinus tarsi just above its floor, ending at the calcaneocuboid joint
- subperiosteally over the anterolateral calcaneus, mobilizing and retracting the peroneal tendons away from the lateral calcaneus.
- A K-wire
- place the pin 1.5 cm proximal to the calcaneocuboid joint, aiming 10 to 15 degrees posteriorly from a direct perpendicular to the lateral calcaneus.
- the graft (iliac crest or allograft)
- 3.5mm lag screw and or staples and etc.
what are Contraindication To Evans?
Severe 1?
Severe 2?
Deformities that can not be corrected passively
Arthritis of the 3?
- Bone metabolism disorder, poor diabetes with neuropathy
- Osteoporosis
- STJ or Chopart joint, stages 3,4 Johnson and Strom
What are some of the Post-op Complications of Evans?
Wound 1?
Delayed 2?
Collapse 3?
4? of bone wedge
Neuritis of the 5? nerve
Stress fracture of the 6?
7? arthritis as a result of impaction
- infections and dehiscence
- bone healing and non union
- of the osteotomy surfaces
- Dislocation
- lateral dorsal cutaneous
- 5th metatarsal
- Calcaneocuboid
What is the Koutsougianis procedure?
based on the book:
By means of an 1? osteotomy through the 2?, Koutsougianis described displacement of 3? fragment medially to lie beneath the 4?
- Oblique 2. body of calcaneus
- posterior (top) fragment
- sustentaculim tali
